Humans naturally think linearly. This is because our lizard brains have evolved over millions of years in environment where linear processes were the most important to understand for survival. When we see a lion that is 1 mile away we know that we have 2x the time to run away than when the lion is .5 miles away. So when we see a crappy project that took a few months to create, we naturally assume that it will be slightly less crappy in a few more months. We can't even imagine what it would look like if it was 100x more useful in 9 months. Even PG and other great early investors only have a slight notion of what that would look like.
